核心需要高斯模糊的库
compile 'jp.wasabeef:glide-transformations:2.0.1'
针对于3.7的版本
使用方法为:
//加载背景, glide.with(musicplayeractivity.this) .load(service.getimageuri()) .dontanimate() .error(r.drawable.no_music_rotate_img) // 设置高斯模糊,模糊程度(最大25) 缩放比例 .bitmaptransform(new blurtransformation(this, 14, 3)) .into(allbg);
针对4.+
glide.with(context) .load(url) .apply(requestoptions.bitmaptransform(new blurtransformation(25,8))) .into(view);
blurtransformation 类源码:
import android.graphics.bitmap; import android.graphics.canvas; import android.graphics.paint; import android.support.annotation.nonnull; import com.bumptech.glide.load.engine.bitmap_recycle.bitmappool; import com.bumptech.glide.load.resource.bitmap.bitmaptransformation; import java.security.messagedigest; import jp.wasabeef.glide.transformations.internal.fastblur; public class blurtransformation extends bitmaptransformation { private static final int version = 1; private static final string id = "blurtransformation." + version; private static int max_radius = 25; private static int default_down_sampling = 1; private int radius; private int sampling; public blurtransformation() { this(max_radius, default_down_sampling); } public blurtransformation(int radius) { this(radius, default_down_sampling); } public blurtransformation(int radius, int sampling) { this.radius = radius; this.sampling = sampling; } @override protected bitmap transform(@nonnull bitmappool pool, @nonnull bitmap totransform, int outwidth, int outheight) { int width = totransform.getwidth(); int height = totransform.getheight(); int scaledwidth = width / sampling; int scaledheight = height / sampling; bitmap bitmap = pool.get(scaledwidth, scaledheight, bitmap.config.argb_8888); canvas canvas = new canvas(bitmap); canvas.scale(1 / (float) sampling, 1 / (float) sampling); paint paint = new paint(); paint.setflags(paint.filter_bitmap_flag); canvas.drawbitmap(totransform, 0, 0, paint); bitmap = fastblur.blur(bitmap, radius, true); return bitmap; } @override public string tostring() { return "blurtransformation(radius=" + radius + ", sampling=" + sampling + ")"; } @override public boolean equals(object o) { return o instanceof blurtransformation && ((blurtransformation) o).radius == radius && ((blurtransformation) o).sampling == sampling; } @override public int hashcode() { return id.hashcode() + radius * 1000 + sampling * 10; } @override public void updatediskcachekey(@nonnull messagedigest messagedigest) { messagedigest.update((id + radius + sampling).getbytes(charset)); } }
